SMOKING-PIPE.

; Specification of Letters Patent.

Patented J an. 18, 1916.

Application filed September 1,1914. Serial No. 859,654.

Moines, inthe county of Pollrand State of} Iowa, have invented a new anduseful Improvement in smokingPipes, of which the following is aspecification.

My invention relates to smoking pipes.

The objection of my invention is to produce a pipe having a. stem andbit in separate parts, and provided with connecting means between saidbit and stem in which the strain of supporting the bowl is sodistributed over the several parts of the structure as to substantiallyapproximate the strength of an integral stem.

A further object of my invention is to produce a pipe stem comprising astem proper, a bit and a connecting screw or plug in which the screw orplug projects into both of said members, and in which the stemtelescopes the bit and the bit telescopes the plug longitudinallywhereby the adjacent vertical edges of the stem and bit contact atapoint offset from the contacting longitudinal faces thereof, andwhereby the supporting strain is distributed over the entire three partsof the structure and the abutting faces of the stem and bit.

A still further object ofmy invention is to produce a more durable andeflicient separable stem and bit for pipes than has heretofore beenattained.

To these ends, my invention includes the combination and arrangement ofcomponent parts to be hereinafter described and more particularlypointed out in the claim.

In the accompanying drawings in which like reference characters indicatesimilar parts, Figure 1 is alongitudinal sectional view of my invention,and Fig. 2 is a detail view of the parts thereof.

Referring to the drawings, 1 indicates the bowl of a pipe'having astem 2integral therewith which is provided with a longicudinal duct connectingwith the bowl. The outer end of the stem is bored to form a projectingring or annular flange 3 designed to telescope and embrace the inner endof the bit 6 as hereinafter described. Adjacent said enlarged bore andring 3, the duct of the stem is enlarged and the wall thereof isinteriorly threaded at 4 to receive the threaded end of the plug 5 asalso later do. scribed herein.

The screw or plug 5, as shown, comprises] the stem portion A and the bitportion 13, the former or stemportion being provided with screw threadson its surface to cooperate with the interior threads in the bore of thestem. The bit portion B. projects beyond the end of the stem and fitsinto the central socket C in the adjacent end of the bit 6. The portionof said bit adjacent to the stem is provided with a projecting annularflange 7 which extends into the ring or fiange 3 on the stem 2 and formsan an nular shoulder D on the bit against which the end of the flange 3abuts when the parts are assembled.

In the ordinary pipe it is well known that the breaking of the stem orbitis frequent, and that the break occurs almost always at thepointwhere the stem and bit are joined together and where their verticalfaces meet. A stem and bit connection embodying the features of myinvention as hereinbefore described, will do away with the weakness ofthe ordinary pipes for the reason that the screw or plug 5 extendsbeyond the telescoping parts of the pipe stem and bit in bothdirections, so that the screw or plug 5 furnishes a reinforcing memberextending beyond all the joints between the stem and bit. In thisconnection it may be mentioned that such construction so reinforces thejoint that the stem and bit will not break at the joint, and will breaksomewhere else first even though the material used for the plug is boneor the like, and if the-plug is made of metal the pipe is practicallyunbreakable at the joint between the stem and the bit. Ifthe plug shouldbe made to extend only to the position flush with the shoulder D, orflush with the end of the flange 3 next to the bowl, the purpose of myinvention would not be accomplished, for with such a construction as isjust mentioned a break would occur inline with one of the partsmentioned. It is important that the screw or plug 5 should extend beyondall the joints between the stem and the bit in order to properlyreinforce such stem and bit and to prevent any breaking at the joints.

It will be appreciated that the parts and combinations thereof may bevaried within a widerange within the scope of the claims withoutdeparting from the spirit and scope of the invention.

Having thus described my invention, what ionrrm) srATEs PATENT camps. IA

- Letters Patent, is-

I claim as new and desire to be secured'by A separable stem for smokingpipes, comprising a bowl stem having ascreW-threaded interior s0cket,'aprojecting annular flange the annular flange on the adjacent bowl,

stem and having a smooth-faced interior socket extending beyondtheflange, and an interior longitudinal plug having screw threads at oneendto engage the interior threads on the bowl stem anda smoth surface onthe opposite end extending-into the socket'inthe bit beyond the flangeon the bit, whereby a separable joint is formed and the strainlofsupporting the bowl is sustained and distributed over all the parts,

substantially asidescribed'. I H v v e l ROY E. 'COMBS.
